2. a kind of operational method of the 10kV circuits according to claim 1 with electrical bonding and dismounting drainage thread apparatus for work,
Characterized in that, be, using WSM points of ditch wire clamps and charged insulating operation instruments, to fix drainage thread and main traverse line point ditch, it is rear to move
Move to main traverse line lap position and block main traverse line, then with charged insulating operation instrument by insulate carrying tool or ground potential it is remote
Carry out stepping up fixing bolt from electrical body；Its step is：
(1) first WSM wire clamps are first fixed on the drainage thread handled well, while main traverse line overlap joint mouth unclamps, are easy to be caught in guidance
Line；
(2) drainage thread and WSM points of ditch wire clamps are moved using instruments such as insulated lock lever, fixing-line device action bars during band electrical bonding drainage thread
Deliver to guide line lap position and be caught in main traverse line；
(3) live-wire insulation tool operating personnel are on insulation carrying tool, bar or ground carries out tightening WSM bolts at a distance.
